Question 1

What is this

Answer 1

NSR

Question 2

Whats going on

Answer 2

Sinus pause AKA arrest

Question 3

whats going on

Answer 3

SA block

Question 4

What’s going on

Answer 4

PAC

Question 5

what’s going on

Answer 5

Ectopic Atrial Tachycardia (atrial foci)

Question 6

What’s going on here

Answer 6

WAP wondering atrial pacemaker (the origin of the electrical charge is mocing around)

Question 7

What’s going on

Answer 7

Multifocal Atrial Tachycardia

This one is just like the WAP but also has an increased HR

Question 8

Whats going on

Answer 8

atrial flutter rate 250+

Question 9

Whats going on

Answer 9

A fib

Question 10

whats going on

Answer 10

Premature junctional contaction

Question 11

whats going on

Answer 11

Junctional escape beat

The SA does not do what it’ supposed to do so another area takes over.

This is when a lower area of function becomes active because the higher areas are not doing what they should

Question 12

Whats going on

Answer 12

Junctional Rhythm

This means the AV node is teh pacemaker

Question 13

What’s going on

Answer 13

Accelerated junctional Rhythym

conduction starting in ventricles with no P waves noted (faster than 20-40)

Question 14

What’s going on

Answer 14

PVC

Question 15

What is going on

Answer 15

Idioventricular Rhythm

Question 16

What’s going on

Answer 16

A fib

Question 17

What’s going on

Answer 17

Escape vs PVC: the escape will be a longer R-R and the PVC will be shorter

Question 18

Junctional Rhythym means it’s coming from where

Answer 18

AV node (40-60)

Question 19

cue that the beat is idio ventricular

Answer 19

There is no P wave 20- 40 BPM unless it’s accelerated

Question 20

What’s going on

Answer 20

Accelerated Idioventricular Rhythm

Question 21

What’s going on

Answer 21

V-tach

Question 22

What’s going on

Answer 22

VTach – Fusion and Captured Beats

Question 23

What’s going on

Answer 23

Torsade de Pointes

Question 24

What’s going on

Answer 24

Ventricular Flutter

Question 25

What's going on

Answer 25

V- Fib

Question 26

What's going on

Answer 26

NSR

Question 27

What's going on

Answer 27

SA pause / arrest (longer than one beat) no big deal if \< 2 seconds ## Footnote SA Node fails to initiate an impulse

Question 28

What's going on

Answer 28

Sinoatrial (SA) Block SA node initiates an impulse but the electrical activity is blocked from leaving the SA node resulting in the absence of P wave, QRS complex, and T wave.

Question 29

what's going on

Answer 29

(1st degree block increased PR) ## Footnote First degree heart block demonstrates a long PR interval. This occurs because the delay through the AV node is too long due to slow conduction in the AV node. The remaining electrical system functions normally. All the P waves are conducted and are associated with a QRS complex.

Question 30

Whats going on

Answer 30

2nd Degree AV Block – Mobitz I (Wenckebach) ## Footnote “longer longer longer drop, low you have a Wenckebach” In type I (Wenckebach), the PR interval increases with each heart beat until it is so long that the signal doesn’t reach the ventricles and the depolarization is “blocked” at the AV node. This beat will show a P wave with no QRS following it. Following the blocked (dropped) beat, the AV node starts again with a normal or near normal PR interval and the cycle repeats itself.

Question 31

What's going on

Answer 31

2nd Degree AV Block –Mobitz II ## Footnote In type II, P waves are randomly blocked just below the AV node. The PR interval is constant, which contrasts with the type I block.

Question 32

Whats going on

Answer 32

3rd degree heart block If the QRS is narrow it originaes near the AV node it wil be narrow. If it’s wide it’s close to PRS. Complete block of the AV node, Atria are paced by SA node, but impulse is blocked to ventricles. Atria are pacing normally but the signals do not make it to ventricles thus you see P waves NOT associated with ventricular escape beats (wide QRS) In third degree block, no P waves are conducted to the ventricles. The SA node generates atrial contractions and P waves. The P waves are 100% unrelated to the QRS’s. Because the ventricles are not being depolarized, an ectopic site within ventricular muscle becomes the new ventricular pacemaker. The ventricular rate is determined by the ventricular ectopic site while the atrial rate is determined by the sinus node. The ventricular beats do not travel retrograde through the AV. The atrial rate is usually faster than the ventricular rate. Understand that both areas of the heart will be pacing REGULARLY, but at their own rates.

Question 33

good review

Answer 33

just a good review

Question 34

If the R is far from P then you have a first degree longer, longer, longer, drop! then you have Wenckebach if some P’s just don’t go through then you have a Mobitz II if P’s and Q’s just don’t agree then you have a third degree

Question 35

Normal Sinus Rhythm (NSR) Rate 60 – 100 bpm Rhythm Regular P waves Upright, all the same, 1 P for every QRS PR interval 3-5 little squares (0.12 – 0.20 seconds), constant QRS complex \< 3 little squares (0.12 seconds)

Question 36

What's going on

Answer 36

Wolf Parkinson White This is asscoated with a delta wave (see how the beginning of the QRS is curved) This is because some of the signal is getting around the AV node and causing slightly early Ventricle deporlaization.
